Application filed November 12, 1917. Serial N 0. 201,522.

To all whom it may concern: Be it known that I, OTIS R. ANGELL, a citizen of the United States, residing at Haverhill, in the county of Essex and State of Massachusetts, have invented certain new ting and burnishing the edges of shoe soles j and more particularly to means for supporting and for reciprocating the operating tool.

In machines of the above type as at present constructed and in which cranks or eccentrics have been employed for reciprocating the tools, much annoyance has been caused by reason of the excessive vibration produced, resulting in disagreeable noise and rapid wear of parts. It is an object of the present invention to so construct a machine of the above type as to eliminate all unnecessary machine parts and at the same time to reduce undesirable vibration to a minimum.

It is a further object of the invention to provide in an edge setting machine a tool holder constructed to simultaneously hold a plurality of tools and adapted to be so controlled as to present either of said tools in working position at the will of the operator.

Other and additional objects and advantages of the present invention together with desirable details of construction and improved combination of parts will be hereinafter described and particularly pointed out in the claims.

Figure 1 is a front-elevation of the head of the machine showing the parts in operative position, certain parts being broken away to show details of construction. Fig. 2 is a side elevation of the tool-holding head, and adjacent parts. Figs. 3 and 4am corresponding views of a modified form of the device, and Fig. 5 is a detail of a wear compensating device.

1 indicates a frame or head which may be of any desired construction. This head is provided with suitable bearings for a shaft 2, said shaft being driven continuously from a convenient source of power, the details of the drive mechanism being omitted herein as forming no part of the present invention. Loosely mounted upon a projecting end of said shaft 2 is a supporting-member 3, said supporting-member being herein shown as in the form of a disk having integral therewith or attached thereto a gear 1. At a point 5 upon the member 1 is pivotally mounted a sector arm 6, said sector arm bej ing provided at 7 with a rack meshing with the gear 4.

At a point 8 upon said arm 6 is a latchmember of any suitable or well known type adapted for engagement with looking openings in a guide-member 11 fixed upon said head 1. By manipulation of latch-member 8-the arm 6 may be freely swung to the right or left about its pivotal support and locked at the end of its movement by engagement of the latch with either of said openings. By the swinging movement of the arm 6 from one extreme position to the other the gear 4: may be rotated substantially one-half revolution and may be locked in either of two diametrically opposed positions, the purpose of which will be hereinafter de scribed. While the above mechanism for rotating the gear 4:, and looking it is well adapted for use in this machine, it is to be understood that the invention is in no manner limited thereto, as any other equivalent devlce may be substituted therefor. No specific claims are made herein to the locking and turning devices.

Projecting from the end of shaft 2 is an eccentric pin 10, said pin engaging within a suitable journal opening in a block 12, said block being provided with upper and lower machined bearing surfaces. At one side of shaft 2 and spaced therefrom a pin or shaft 13 projects from the face of said support 3, said pin being held in fixed relation within said support by means of set screw 14 or other suitable equivalent means, the pin being provided at its outer end with a head 15. Between said head and the support 3 a tool-carrying head 16 is pivotally supported upon the pin 13 to rock thereon, said head being provided with a pair of spaced apart arms 17 and 18 extending in the direction of the shaft 2. The arms 17 and 18 provide opposed bearing surfaces 19, 20 for engagement with the corresponding bearing surfaces of the block 12, thus permitting a free sliding movement of the block with respect to the head 16.

Projecting upwardly and downwardly from said head 16 are posts 21, 22 carrying at theirextremities members 23 and 24 respectively adapted for the mounting thereon of'the usual tool holders employed in this type of machine. Theposts-Ql and :22 may, if desired, be slotted as at 25 to make the parts lighter and save material-in manufacture, this, however, not being a necessary part of the invention.

The operation of the mechanism above described will now be obvious. parts shown in the position of Fig. 1 rotation of the shaft2will cause the block 12 to move in a circular path. By reason. of the slidable engagement of the block with the bearing surfaces of the head 16, the latter .Im y 'be so turned about the shaft 2 asa: center as to reverse the, position of the tool holders, thereby permittingthe use of either of the tools at the will of the operator.

While the above is a preferred embodiment of the invention the devices shown-in Figs. 3 and kmay be at times. found-de- .sirable. As in thesefiguresv many of the parts correspond instruct-Lire andfunction to those of the form hereinbefore described, it will be only necessary to describe such parts briefly as follows :2 is the drive shaft; 3 the supporting member; 4% the gear fixed thereupon; 13 the pintle pin; 14 the set screwtherefor; 1'6 the tool-car- ,rying head;.23- and 24: the members. for

carrying the tool holders and 10? the eccentric pin projecting from the end of the shaft.

In the present embodiment oft-he inventionthe tool-holding head16 is provided with opposed arms 21 and 22 having po-rtions 30 and 31 extending in the direction oft-he shaft 2 The parts 30 and 31v are slotted at 40* to provide opposed armsea-nd j bet-Weensaid arms are pivoted, asbymeans of pins 32, 33, a pair of rollsa34, :35, said 7 rolls being arranged for direct contact with the eccentric pin'or camlO";

It is to be understood that suitable means may be provided for turning the gear 4Pthro-ugh180 degrees and for locking the samein either extremity of its movement asin the previously described embodiment.

The operation of the presentmodifioation will nowbe clear. Upon rotation of the shaft '2 the eccentric pin 10 contacting with rolls 34; and 35 will cause an upward and downward swinging: movement of 5 the: same about. the pintle pin 13*, thus causing a rocking movement of the head andthe'tool With the holders carried thereby. Reversal of the tools for alternative operation of the same will be brought about in-th'e manner herein before described with respect to the preceding modification.

Having now thus described the invention and a specific embodiment thereof as well as the function and mode of operation of the same, .what Iclaim as new and desire to secure by Letters Patent of the United States is, 7
